Presence of H2S in the fuel can have adverse effect on the performance of Solid
oxide fuel cells (SOFCs) because it can poison the Ni-based anodes. Poisoning
occurs by sulfur adsorption on the electrochemically active sites on Ni. This
study is aimed at predicting the effect of the sulfur poisoning on the
performance of SOFC with porous Ni- YSZ anode.
The paper consists of two parts: (i)
Modification of the kinetic expression for hydrogen electro-oxidation reaction
at anode, and (ii) Implementation of the new kinetic formulation to an existing
along-channel twodimensional porous Ni-YSZ half-cell model.
